摘要:The synthesis of omega-hydroxyalkyl-urethanes, and of alfa-omega-diurethanes is reported which includes the reaction of diols with urea in presence of catalysts based on Ce at temperatures between 125 and 170°C over 4-8 h reaction time. A process for the production of oligomers of omega-hydroxyalkyl-urethanes is also reported based on the reaction of urea with diols in presence of Ce or Zr catalysts or Ce mixed oxides at 125-170°C over 4-20 h.

权利人:YISSUM RES DEV CO
摘要:The present invention relates to racemic propylisopropyl acetic acid and propylisopropyl acetamide and their isomers in their racemic and stereospecific forms, for use in treatment of neurological and psychotic disorders, and affective disorders and to treat pain, headaches and migraines. The isomers are of the compound formula I:wherein R1 is a methyl or ethyl group; R2 is H, methyl or an ethyl group; R3 is ethyl or a propyl group; and R4 is a hydroxyl or amide group; and the total number of carbon atoms in said compound is 8, provided that when R1 is a methyl group and R4 is an amide group, R2 and R3 are not ethyl, further provided that when R1 is an ethyl and R4 a hydroxyl group, only stereoisomers of the compound are referred to. The present invention further relates to a method for the stereoselective synthesis of the 2S and 2R stereoisomer of PID and PIA. The present invention also relates to pharmaceutical compositions containing as an active ingredient a racemic mixture or stereoisomers of the compounds of the general formula (I), which are useful for the treatment of neurological and psychotic disorders, and affective disorders and to treat pain, headaches and migraines.

权利人:MORTKO HENRY; HE WEIXUAN; ANDERSEN MARC W; DOTSE ANTHONY K; LI JIE
摘要:Disclosed is a method of making 2-substituted-2-halo-1,3-propanediols via reduction of corresponding malonate compounds. Also disclosed is a method of making 2-substituted-2-halo-1,3-dicarbamate compounds (such as halo derivatives of felbamate, including fluorofelbamate) via reduction of malonate compounds, followed by carbamoylation. Reduction of the malonate compounds is carried out using an electrophilic hydride reagent.
